BINDER.

Application filed March 23, 1923. Serial No. 627,003.

To all 1071 0722. it may concern:

Be it known that I, CHARLES H. FRANZ, Jr., a citizen of theUnitedStates, and resident of Milwaukee, in the county of Milwaukee and Stateof lVisconsin, have invented certain new and useful Improvements inBinders; and I do hereby declare that the following is a full, clear,and exact description thereof.

This invention relates to binders and is particularly directed to looseleaf binders, which are adapted to be carried from place to place.

In binders such as those used by traveling salesmen, it has beencustomary to provide substantial covers which fully protected the frontand back of the pages but ex posed the margins to dust and rain. Thisnecessitated either the complete wrapping of the catalogue or book orthe provision of a separate case therefor, but even with theseprecautions the leaves soon become unsightly from the soot and dirtwhich rapidly accumulated upon such leaves.

This invention is designed to overcome the above noted defects, andobjects of such invention are, therefore, to provide a binder for looseleaf books, such as catalogues, which will not only form the backs butwill also fully and adequately protect all por tions of the book fromdust or rain, which will accommodate a large number of loose leaves,which permits their ready removal or insertion, and which may be readilyopened out flat to fully display any desired sheets and which may beinstantly closed to thereby completely house the sheets.

An embodiment of the invention is shown in the accompanying drawings, inWhich- Figure 1 is a perspective view showing the binder and theenclosed sheets opened out flat.

Figure 2 is a perspective view showing the device in the closedposition.

Figure 3 is a side elevation partly in section, to illustrate theinterior construction, such figure corresponding roughly to a section onthe line 33 of Figure 2.

Figure 4c is a sectional view on the line 4-4 of Figure 3.

The binder comprises a pair of binding strips 1 and 2 of reinforced andsturdy construction, which are adapted to receive between them the loosesheets 3. A pair of back plates 4 and 5 extend inwardly from the bindingstrips and are overlapped and slidably related, as may be seen fromFigures l and 3. Any desired means may be employed for holding thebinding strips in engagement with the leaves, for instance, an expansionbolt 6 and a sleeve 6 may be employed, such sleeve being convenientlyattached to the back plate 5, as illustrated in the drawings. Theseexpansion bolts and associated sleeves may extend through apertures inthe sheets in the usual. manner.

A pair of reinforced covers, 7 and 8, are provided and are attached tothe correspond ing binding strips by means of flexible hinges, asindicated at- 9 and 10, preferably formed from leather or similar easilymanipulated material. A convenient Way of attaching these strips to thecover is illustrated in Figure 3, from which it will be seen that thestrips are received within an inner ply of the cover and the remainingplies thereof and stitched in position. This construction forms awaterproof joint between the covers and the binding strips. Each of thecovers is provided with a U-shaped strap member, having its legs 11stitched across the face of the cover, as illus trated in Figures 2 and3, to form a secure attachment for the curved portion 12 thereof, whichportion is utilized to form acomposite handle. In this manner not onlyare the covers further reinforced, but the strain from the handles isdistributed over a material portion of the covers and is not calized atany one point. If desired, the curved handle portions 12 may havereenforcing rods 13, (see Figure 3), to stilfen them. A strap 1% may beattached to one of the handle portions, and may be provided with snapfasteners so that it may be wrapped completely around both of theportions of the composite handle and snapped in place to form aconvertible handle and a simple means for holding the covers in closedposition.

In order to protect the marginal edges of the book from dirt, dust andrain, inwardly directed flanges are provided along the three freemargins of the covers. The flange 15 of the cover 8 may be overlapped bythe flange 16 of the cover 7, and it is to be noted that these flangesoverlap a ma terial distance so as to form an effective and serviceableprotecting joint to prevent entrance of harmful matter. It is to benoted that the flanges continue in unbroken formation completely aroundthe three edges of the cover and are free from the back plates 4 and 5to permit the complete opening up of the book, as illustrated inFigure 1. When, however, the book is closed, the flanges and 16 overlapthe, end margins of the back plates, as may be I seen from Figures 2 and4, thereby com Lat pletely protecting the leaves from the on trance ofrain or dust.

It will be. seen that a binder has been provided which is adapted toaccommodate anydesired number of leaves, and which is at all timessecurely attached to the leaves. This provides a binder which in effectforms a portion of the composite book.

.It is further to be noted that the overlapping back plates andthe'overlapping flanges '15 and 16 completely house the leaves, and

Y the free edges of said covers to completely house thevleaves when thebook is closed,

and a pair of strap handles secured to said covers and adapted to form acomposite handle when 'said book is closed.

2'. A binder for loose leaves comprising binding strips, adjustablemeans connecting said strips and binding the leaves between them, a pairof overlapping back members extending from said strips, relatively stiifcovers hingedly joined to said strips, and flanges extending inwardlyfrom the free edges of said covers and telescopically related tocompletely house the leaves when saidv covers are closed. 7 I

3. A binder for loose leaves comprising a pair of binding strips adaptedto hold the leaves between them, adjustablebolts connecting said strips,a pair of slidably related overlapping back plates carried by saidstrips, a pair of reenforced covers joined to said strips by flexiblematerial,

inwardly directed telescopic flanges carried by said covers and adaptedto overlap the ends of the back plates, and a U-shaped strap for eachcover having its legs secured across the face of its corresponding coverand having its curved portion projecting therefrom.

In testimony that I claim the foregoing I have thereunto set my hand atMilwaukee, in the county of Milwaukee, and State of Wisconsin. CHARLES'H. FRANZ, J R.
